Motor Mounts ?

[red98gt]

I know there are three motor mounts, I have replaced the upper, and lower, but how/where is the middle mount? Is it a 'driveway' fix or do I take it to a shop?

You'll have to remove the lower & upper mounts to jack up the engine in order to replace the middle mount. The middle mount rarely goes bad.

replacing the mid motor mount

What diagnosis is encouraging you to replace the middle mount?

I have a shimmy when pulling away from a traffic light, going up a hill, and right/left turns. I have replaced the lower and upper mounts which both were bad, and thought to also replace the middle one as well thinking it too might be bad. I have an 07 with 54k miles and have had this shimmy for awhile now, and it had a shimmy when I bought it. I started out by getting new tires and wheels along with a front end alignment and balancing. Still had a shimmy, but better... then I replaced the lower control arm bushings and link end bushings, still had a shimmy, but better... then I replaced the upper and lower motor mounts, still had a shimmy, but better still. Now I'm at my wits end, and don't know where to go next. I've spent hundreds of $. Not being a mechanic, I ask questions where I can. I was told to also try tie rod ends, and to get the wheels balanced again @#$%#@!

Just going to put this out there...and incur the wrath of Nitro...

My 2005 has a shimmy. When I purchased it used, it would show up above 50 mph and go away around 55mph.

Completely unrelated, I changed out the spark plugs and wires around 3 to 6 months...and the shimmy wasn't as bad (hardly noticable) and it moved to above 55 mph and goes away around 60 mph. It was the only change I made and doesn't make any sense to me. But I figured I would put it out there!

Have you checked the Transmission Mounts..??

What do you fell the shimmy in? Steering wheel, gas peddle , or seat?

Thanks 'hoghunter', car runs like a dream. I have not checked the trans mount, but a good thought 'lionpt'. and 'bustedpt', the feel is in the steering wheel and seat. Thanks guys for your info!

Then you can rule out powertrain. Look carefully at the wheels, tires, hubs, bearing, tie rods, and ball joints.

Have you checked both of your front wheel bearings?
